Ions And Ionic Bonding

Question 1

What is an ion?

Answer 1

An ion is an atom, or group of atoms with a positive or negative charge

Question 2

Which elements does ionic binding occur in?

Answer 2

Metals and non-metals

Question 3

What happens in ionic bonding?

Answer 3

Atoms either gain or lose electrons from one another, forming ions

Question 4

What is an ionic compound?

Answer 4

Compounds made up of ions

Question 5

Ionic compounds are arranged in..

Answer 5

• A regular 3D arrangement
• Giant lattice
• With strong electrostatic forces
• Positive and negative ions

Question 6

Properties of ionic compounds

Answer 6

• Solid at room temp (strong electrostatic forces, resulting in high melting points)
• Don’t conduct in solid state (ions can move around and carry a charge
• Conduct when liquid/molten (bonds break so ions are free to move and carry a charge)
• Brittle (extremely strong bonds - applying pressure to the rigid lattice structure causes them to move and break)
• Soluble (water breaks down the lattice)
